Your front tires are extremely tall, and while you don't want to size down the tires up front, you probably should!

Hate to be the one to tell you but you need to get the right tires. The diameters of your current tires are different by 3% which is where the VDC starts to have issues.

Yes I know there too tall but thats not what im asking im asking what size would in need in the back to make it work theres some guy with 26's on his I personaly dont like it but thats what he wants and I want to keep the tall tire up front just need to know what would work with the back wile still keeping the with 285

You're larger than OEM.... you need smaller tires.

See me in my office.

This post is pointless imma just have to try it ill let u know what works

Your loss.

If you're running 285s in the rear right now you could size down the sidewall height on the fronts and still keep the rear tires.

There really isn't a tire that's going to have the correct oversized outside diameter that will work properly and not rub. You would be better off buying the correct front tire size than trying to get another incorrectly sized rear tire on there.

245/45/19 ↑ they fit no rubbing no problem ...

They shouldn't rub at stock height. Oh, and get the RIGHT size tire...

No !!!

I'm not understanding this part, please elaborate on how that matters.

And this will provide your answer: http://www.miata.net/garage/tirecalc.html. The difference between the overall diameter of the tires must be smaller then 3%.
